2001 Infiniti Trucks Tire Fitment Guide

2001 Infiniti Trucks coverage centers on the QX4, which uses two tire sizes: 245/65R17 and 245/70R16. The 245/65R17 mounts on a 17-inch rim and works with a 7.0 to 8.0-inch rim width range, while the 245/70R16 mounts on a 16-inch rim and works with a 6.5 to 7.0-inch rim width range. Both are radial sizes, but they are tied to different wheel diameters.

That means a 2001 Infiniti Trucks owner cannot choose between the two sizes by preference alone. The practical first check is the actual wheel on the vehicle, because a 16-inch tire will not fit a 17-inch wheel and vice versa. Once wheel diameter is confirmed, the choice becomes straightforward, and you can then compare load capacity, sidewall style, and intended use within the correct size.

On a 2001 Infiniti Trucks QX4, 245/65R17 is a metric radial size. The 245 is the nominal section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. In this fitment, the tire carries a 111S service description, with S indicating a 112 mph speed ceiling.

For a QX4 owner, that code tells you both physical fitment and the tire's construction type at a glance. It is the correct language to match against the sidewall of the tire already on your truck or the wheel diameter you know you have. Matching the full size code is the safest starting point before comparing tread style or brand preference.

The 2001 Infiniti Trucks range covered here includes the QX4, and that model does not use a single universal tire size. The QX4 appears with either 245/65R17 or 245/70R16, depending on its wheel package. Both fitments are radial, but the wheel diameter changes with the tire size.

That distinction matters even though there is only one model name in the range. A buyer who knows they have a 2001 Infiniti Trucks QX4 still needs to verify whether the vehicle is on 16-inch or 17-inch wheels before choosing tires. Checking the sidewall on the existing tire or measuring the wheel diameter is usually faster than trying to identify the fitment by appearance alone.

A 2001 Infiniti Trucks QX4 owner should choose between 245/65R17 and 245/70R16 based on wheel diameter first, not by treating them as interchangeable options. The 245/65R17 is built for a 17-inch rim, while the 245/70R16 is built for a 16-inch rim. Both are radial all-terrain tires in the available BFGoodrich offering, so the main fitment difference is the wheel itself.

If your QX4 still has its original wheel package, staying with the matching size keeps the tire properly seated and preserves the intended relationship between tire and wheel. If the truck has changed hands or has aftermarket wheels, confirm the current wheel diameter before ordering. That one check prevents the most common year-make-level mistake on a vehicle with two valid factory size paths.

The available 2001 Infiniti Trucks QX4 tires in both 245/65R17 and 245/70R16 come with an RWL, or raised white letter, sidewall style. That look fits naturally with an early-2000s SUV and light-truck theme, especially on an all-terrain tread where the sidewall treatment is part of the tire's character. There is no sidewall-style split between the two sizes here.

For an owner trying to preserve the right visual tone, RWL gives the QX4 a distinctly period-correct sport-utility appearance without pushing it into a vintage bias-ply aesthetic that would not suit this era. If appearance matters as much as fitment, confirm whether you want the white letters facing outward before installation, since that can affect the final look even when the tire itself is the same.

BFGoodrich covers both 2001 Infiniti Trucks QX4 sizes here. The 245/65R17 and 245/70R16 each appear in the BFGoodrich All-Terrain T/A KO2 series, both as radial tires with RWL sidewalls. That gives the year and make a consistent brand and tread-family approach across its two wheel diameters.

For the buyer, that consistency simplifies the decision because you are mainly sorting out the correct size rather than weighing multiple brand personalities within the same fitment. Once the wheel diameter is confirmed, the remaining comparison is more about how an all-terrain tire fits your QX4's use, appearance, and load needs than about cross-shopping several different brand options.

The two 2001 Infiniti Trucks QX4 tire sizes use different rim width ranges. The 245/65R17 fits a 7.0 to 8.0-inch rim width, while the 245/70R16 fits a 6.5 to 7.0-inch rim width. Each size also requires its own matching wheel diameter, 17 inches for the first size and 16 inches for the second.

That means wheel diameter alone is not the only fitment check worth making. A QX4 owner changing wheels, replacing a single damaged wheel, or working with an older aftermarket wheel set should confirm both diameter and width before mounting tires. Staying inside the proper rim-width range helps the tread sit correctly and preserves the tire's intended shape under load.

The available 2001 Infiniti Trucks QX4 tires are radial light-truck products with no tube-type marking in the size description. That points to tubeless fitment rather than a tube-type application for both 245/65R17 and 245/70R16. On a modern SUV such as the 2001 QX4, tubeless construction is the normal expectation.

Even so, the wheel still needs to be in suitable condition for tubeless service. If the truck has replacement wheels, corrosion at the bead seat, or old valve stems, those issues should be addressed during installation. A clean sealing surface and fresh valve hardware matter just as much as choosing the correct size when you want a tire to hold pressure reliably.

A 2001 Infiniti Trucks QX4 should be stored on clean, properly inflated tires away from direct sunlight, standing moisture, and ozone-producing equipment such as electric motors, welders, or air compressors. Because both available sizes are radial, they generally tolerate periods of storage better than older bias-ply designs, but they still age from environment and inactivity. Keeping the vehicle on a dry surface and moving it occasionally helps reduce flat spotting and casing stress.

If the QX4 sits for long periods, many owners either roll it a short distance from time to time or place it on stands in a way that reduces sustained load on the tires. Either approach can help preserve shape and sidewall condition. The key is to avoid leaving an underinflated tire supporting the vehicle in one position for months at a time.

On a 2001 Infiniti Trucks QX4, tire life is usually judged by age as much as by tread depth. Collector and low-mileage SUVs often wear out their tires chronologically rather than through heavy mileage, so a five-to-seven-year evaluation window is sensible, with around ten years being a common point for serious replacement consideration. The DOT date code on the sidewall is the starting point for that conversation.

A tire can still look usable from a distance and yet be old enough to deserve closer scrutiny. Sidewall cracking, hardening, vibration, and a history of long static storage all matter. If your QX4 sees occasional weekend use rather than daily driving, make age checks part of routine maintenance instead of assuming low miles automatically mean the tires are still serviceable.

Tires on a 2001 Infiniti Trucks QX4 should be inspected before every drive and again before any longer highway trip. Look for cuts, bulges, exposed cords, irregular wear, pressure loss, and sidewall cracking, and confirm that the valve stems are in good condition. On a vehicle of this age, that habit matters even when the tires have plenty of remaining tread.

A quick pre-drive inspection takes very little time and can catch problems that develop while the vehicle is parked. For longer outings, check the spare as well, since many occasional-use SUVs still carry an aging original or an older replacement. Pressure, tread condition, and visual sidewall health should all be part of the same routine, not separate afterthoughts.

A 2001 Infiniti Trucks QX4 would have been built for modern radial tires, not bias-ply construction. The two fitment paths used here are 245/65R17 and 245/70R16, each tied to its corresponding wheel diameter. For a vehicle from this era, the original-equipment question is usually more about confirming the exact size and wheel package than about choosing between vintage construction types.

Owners pursuing a factory-correct look should start with the size shown on the vehicle's original tire placard, owner's literature, or surviving original-spec references for that exact truck. If the QX4 has changed wheels over the years, the current tire may not reflect how it left the factory. A marque specialist or Infiniti-focused enthusiast group can help confirm market- and equipment-specific details before a restoration-minded purchase.

Correct tire fitment does matter on a 2001 Infiniti Trucks QX4 if the goal is a factory-faithful presentation. On a neo-classic luxury SUV, judges and informed enthusiasts will notice an incorrect overall size, the wrong wheel diameter, or a tire style that looks out of step with the truck's original character. Because this era already belongs to the radial age, the fitment conversation is about matching the proper modern size rather than preserving a pre-radial construction.

For most shows, accuracy starts with the right 16-inch or 17-inch package and a sidewall appearance that suits the period. Event standards can vary, especially between marque-focused judging and general enthusiast shows, so it is smart to check what your club or event emphasizes. If authenticity is central to the build, verify the exact wheel-and-tire combination before making cosmetic choices.

Sidewall appearance on a 2001 Infiniti Trucks QX4 is not as dominant a judging point as it would be on a pre-war or muscle-era restoration, but it still influences how correct the vehicle looks. The available tires here use an RWL sidewall, a style that fits the rugged-luxury SUV image common in the early 2000s. On a truck with the right wheel package, that visual treatment feels more natural than an overtly vintage sidewall design would.

For an owner restoring or preserving a QX4, sidewall style is usually the finishing detail after size and wheel diameter are confirmed. It affects the truck's stance and period feel more than it affects basic fitment. If your goal is a near-stock presentation, compare the look to original photos, brochures, or survivor vehicles so the final appearance matches the era as closely as possible.

The available 2001 Infiniti Trucks QX4 tires carry S speed ratings in both sizes, which corresponds to a 112 mph ceiling. That is comfortably above normal U.S. highway speeds, provided the tires are in good condition, properly inflated, and matched to the correct wheel size. On a 2001 luxury SUV, overall roadworthiness also depends heavily on suspension condition, alignment, brakes, and steering components rather than on speed rating alone.

In practical terms, a sound QX4 on fresh, correctly fitted tires should be entirely capable of normal highway use. The bigger concern on an older vehicle is often age, wear, or neglect elsewhere in the chassis. Before any sustained freeway driving, confirm the tires are not aged out, check for even wear, and make sure the vehicle itself is ready for the trip.

The two 2001 Infiniti Trucks QX4 tire sizes carry different maximum load-and-pressure figures. The 245/65R17 is rated at 2,405 pounds at 65 psi, while the 245/70R16 is rated at 2,535 pounds at 65 psi. Those figures describe each tire's maximum rated capacity point, not necessarily the pressure your QX4 should be driven at in normal service.

For everyday use, start with the vehicle's original recommended inflation pressure from the door placard or owner's manual, then confirm that recommendation still makes sense for the exact tire type fitted. Reproduction and modern replacement tires can differ from the original equipment tire's construction and load range, so it is wise to cross-check the tire manufacturer's guidance rather than transferring assumptions from one size to another.

Before a longer trip in a 2001 Infiniti Trucks QX4, inspect all four tires for cracking, punctures, bulges, uneven wear, and proper inflation, and make sure the spare is usable as well. Confirm that the truck is on the correct 16-inch or 17-inch tire size for its wheels, and check valve stems for age or damage. Those basics are especially important on an older SUV that may spend part of the year parked.

Tires are only one part of the readiness check, but they are the part in direct contact with the road. It also makes sense to look over brakes, fluids, belts, hoses, lights, and suspension before putting miles on a neo-classic Infiniti. A calm walk-around and a few minutes under the hood can prevent a small issue from becoming a roadside problem.
